This may interest some of you who would like to read an article about the trout residency work and stocked trout tracking via telemetry, which was done by Rob Wnuk, AFM for the upper Susq R basin. The map contained within the article will interest you if nothing else does because it shows geographically within Pa where most of the residency problems had been found and where they have typically been found since the article's publication. You will note that some of the methodology followed by AFM's and their crews, as mentioned in the article, has since been modified as we have learned more about the problem.

Thanks Mike, an interesting study no doubt. B.Anderson of the LJRA also conducted a telemetry study done on the Little J, he was to announce his findings last week at their monthly meeting. Was not able to make it, but would have liked to see the difference between the wilds and stocked.

And in other streams a lack of structure (boulders, undercut tree roots, downed trees, secondary channels) that provide places for trout to hide from high velocity flows. So the trout are just getting blown downstream by high flows.

Many stream miles are essentially man-made, channelized ditches, with very little structure. This is especially true in the glaciated counties of NE PA, such as Bradford and Susquehanna Counties.
